MADSKY interview questions

An internal recruiter asked me to apply on Indeed. I was at the beginning of my job search and the job looked similar to what I was previously doing. Had a phone screen on a Friday, and it went well. They mentioned they were going on vacation and I would hear back not the following week, but the week after when they returned. Never heard from them, even after a couple follow ups. Very unprofessional to not let candidates know either way.
